The Holy Spirit is given by measure?

Why haven’t most Christians received the Holy Spirit, if He has already been sent?
What has stopped you from being sealed with the Holy Spirit?

Is it your lack of faith? Of merit? A complete surrender?
There are many reasons.
I believe the biggest obstacle that has prevented the Holy Spirit from pouring down upon the life of many has been their lack of a total commitment.
Receiving Him means you receive His Fullness or Plenitude.
Those who are willing to receive Him must be willing to sacrifice their life.
It is God’s All for your all.
Unfortunately, not everyone is truly willing to give up their life or their sins.
They might accept Jesus as their Savior, but they do not want Him as their Lord.
They want to enjoy a life without restrictions, without any serious commitments to anyone. Not even Jesus.

We can’t tell who someone really is by what they show us on the outside, but the Holy Spirit looks deep inside.
This intimate encounter will reveal the absence of the Spirit of God in the person’s life.
He pretends that Jesus is the Lord and Savior of his life.
He pretends to be faithful to Him. He pretends to be spiritual. He pretends to seek Him. He pretends to be of God. He pretends, pretends and pretends...
Years go by and he keeps pretending.
There is a saying used by politicians that goes: I’ll pretend like I’m going to keep my word and you pretend to believe me. And we each help ourselves the best way we can.
Of course the Spirit of God does not pretend to believe in someone’s surrender. But, because He knows what is truly deep within that person, He is saddened.
On the other hand, the devil enjoys it.
And his life will indefinitely remain tied-up.
He will attend church meetings, be a tither, make vows, pray, cry out to God, but will continue refusing to give up the liberty to sin.
Jesus said: "He who believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides in Him." John 3.36

Note: In the Bible, the word believe means unconditional surrender of the body, soul and spirit.
